IB Psychology - Biological approach
Terms in this set (32)
Neurotransmitter released by certain neurons in the brain and is part of the human 'fight or flight' response with increased heart and breathing rate with pupil dilation response.
The area of the brain that is responsible for detecting emotions, especially fear.
The long, slender projection of a neuron that conducts electrical impulses away from the neuron's cell body.
An organism's external reaction to its environment.
The brain's ability to change and adapt as a result of experience.
A region of the brain that contains neurons involved in speech function located in the left frontal lobe.
The tentacles around the cell body of a neuron that receive the neurotransmitter.
The system of glands that secrete various hormones into the blood system
The interaction between the genotype and the environment resulting in the phenotype.
A theoretical approach that attempts to explain useful mental and psychological traits as the functional products of natural selection.
Positioned at the front of the cerebral cortex and are involved in movement, decision-making, problem-solving, and planning.
The study of how genes affect behaviour
It is associated with memory including spatial navigation as well as regulating emotions.
Chemical messengers released into the blood from endocrine glands.
The area of the brain that controls the pituitary gland. It also regulates homeostasis.
The use of various techniques to either directly or indirectly image the structure, function, or pharmacology of the brain.
Different parts of the brain are responsible for controlling different behaviours
The switching off and on of genes which can change the activity of a DNA segment without changing the sequence.
The neuron that fires when a human observes and imitates the same action made by another.
Forming new neural connections are the brain develops
The process by which neural connections that are no longer needed are removed due to the strength of the connection
A specialised nerve cell that receives, processes, and transmits information to other cells in the body.
When an electrical impulse travels down the body of a neuron (axon body), it releases neurotransmitters which cross the gap between two neurons known as the synapse
A chemical messenger in the brain that stimulates a range of physical and psychological processes.
The visual processing area of a mammalian brain.
Hormone released by the pituitary gland and is responsible for human behaviours associated with relationships and bonding - e.g. the love hormone
Chemical signals that are released by both animals and humans that send olfactory (scent) messages to other members of their own species.
A neurotransmitter that is involved in with sleep, depression and memory (along with other psychological processes)
The junction between two neurons where there is a small gap that neurotransmitters help nerve impulses to cross.
Process by which more synapses are generated as an individual encounters new stimuli.
The part of the brain that is able to understand and recognise language. Located in the rear of the left temporal lobe.
Hormone released by the adrenal gland in times of stress.
